BUCKET. y

Specification of Letters Patent.

Patented Mar. 13, 1917.

Application filed May 9, 1914-.. Serial No. 837,883.

To all whom 'it may concern.'

Be it known that I, PHILIP M. ARM- srnonc, a citizen of the United States, residing at Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Buckets, of which the following isa full, clear, and exact specification, suchl as -will enable others skilled in the art to which it appertains to make and use the same.

This inventionv relates to excavating buckets, and while I have shown, and will more particularly describe it, as applied to a dwarf or hand operated orange peel bucket, it is to be understood, that it may be applied to other types of buckets as well as the orange peel, and also to standard or full sized, power operated buckets.

The use 4of dwarf, or hand operated orange peel buckets has now become quite general, being especially adapted for use where the operating space is limited, as for example, in foundation work, tunnel excavations and the like, where they are frequently used for excavating rock, earth or other materials, from small steel cylinders which are driven into the ground preparatory to forming piles, by'depositing concrete therein. One serious drawback to the use of dwarf orange peel buckets, in such work, has been that owing to the small size of the buckets, and their relatively small weight, compared to the standard or full sized buckets, their capacity for penetrating the ground when hard material is encountered, is greatly lessened, and one of the objects of my invention is to overcome this diiiiculty. Y

I accomplish the desired result by providing means at the head of the bucket for applying force thereto, to drive the digging points of the blade into the material to be excavated, when occasion requires.

A further object of my invention is to apply this force by means of a device which may be readily detached from the head of the bucket so that the bucket may be used in the ordinary way without this attachment, when there is no necessity for its use.

vAnother object of my invention is to provide an attachment of the character stated, which is simple and economical to make, to

apply, and to operate, and in no wise interferes with the usual operation of the bucket to which it is applied.

All of these objects will be readily apparent from the following description,

'taken in connection with the accompanying drawings, 1n which- Figure 1, is a side elevation of a dwarf orange peel bucket with my driving attached from the bucket.

Referring to the construction illustrated,

ik, represents in its entirety, an orangepeel bucket, of a usual and wellknown type, of which only a brief description will be necessary. It comprises a supporting head, B, connecting rods C, pivotally suspended therefrom, a plurality of digging blades D, a power wheel E, rotatably 'mounted in a frame F, said power wheel being rotated by a closing line G, and, with the frame F, raised and lowered by means of side chains H, which wrap about a hub I, on each side of the power wheel, the arrangement being such that as the power wheel E and the frame F are raised and lowered, the digging blades D, are respectively closed and opened. Referring now in detail to the novel features illustrated in the drawings, and more led atv J', and secured to a weight guide socket yK, by means of the interior threads J2 therein, which guide socket is adapted to be removably. secured to the head B of the bucket. The weight guide socket K, comprises an impact block, of circular form, K (see Fig. 4) from which'are depending side lugs, K2 K3, which are adapted to rest upon the head B of the bucket, andare 'secured thereto by means of bolts K4 passing through the lugs K2 K3 and through an upwardly projecting lug K5 on the bucket head. The guide J is formed with an eX- ternal shoulder L, and the inner wall of the Weight H is formed With a shoulder M, so that when the Weight H is raised, the shoulder M contacts with the shoulder L, and thereby is prevented from riding oii' the guide. A portion of the shoulder L, at each side thereof, indicated at L, as Well as the opposing Walls L2 of the Weight H are plane surfaces to prevent rotative movement thereof, on the guide J.

The guide J is formed with a longitudinal bore therethrough, indicated at N, through which may pass the closing rope G..

The Weight H is recessed at each side thereof to receive the ends of a shackle (Y), secured thereto by bolts l.

The ivcightmay be manipulated by grasping the shackle (l, or, when the operation is .below the surface or if the bucket be power operated, by means of a rope Q, secured to the shackle, operated by hand or other power.

The shackle O is so formed that when in operation the pull thereon is at directly opposite sides of the Weight H, and when not in operation. it takes its place by gravity at one side so asto be out of line, and not interfering, with the closing rope, G.

Dwarf orange peel buckets for such purposes as stated herein, I have found to Work very satisfactorily With a hammer device, weighing yapproximately one third the total Weight of the bucket Without the hammer device. e

The operation of the d vice is as follows: Assuming that the bucket is on the material to be excavated, and in the open position shown in Fig. l, and assuming that the material is too hard to permit ready penetration of said material by the blades, the shackle 0 is either manually grasped by the operator1 or manipulated through the rope Q attached thereto, to lift the Weight H to the position indicated in dotted lines in Fig. 1, the same sliding on the guide d; .it is then released, and, in falling, it imparts a bloiv to the face K of the Weight guide socket K, which blow is transmitted through the 'lugs K2 l73 tothe supporting bucket head B, and thence, through the rods C vto the blades D. ri few blows thus given will suffice to drive the digging points of the blades D, into the material. The closing line G, is then actuated to rotate the power Wheel E, the chains H Winding upon the hub members l, raising the frame F, thereby closing the blades, and in this operation it will be seen that as the rope Gr, passes through the bore of the guice d, its operation is in no Wise interfered With by the Weight H. When the bucket is closed, the rope Q, may be operated as a holding line in conjunction with the rope G) and in so doing, the Weight H Will rise to the position indicated in dotted lines in Fig. l, and Will be so held until the bucket has been swung to a position Where the material is to be dumped, When the closing line G is eased off to permit the opening` of the blades, and, so held, the bucket is Wung into position to take a new load of material.

lfhen the bucket is to Work in material easily penetrated, and it is unnecessary to use the hammer device, the bolts K4 may be removed, the hammer device lifted from its position on the head of the bucket, the shackle R, (shown in Fig. 5) secured to the head K5 by means of the centrally located bolt K4 and the bucket operated in the ordinary Way.

i desire it to be understood that l do not confine myself to the precise details of construction and arrangement of the ,invention herein set forth, as modifications and variations may be made Without departing from the spirit 0f the invention, as deiinedby the ,appended claims.
